FIG. 3 is a flowchart showing an example of calculating a capability score in operation S300 according to an embodiment of the present invention. - Referring to
FIG. 3 , in operation S310, the number of patents per unit time is calculated based on unit time and time information with respect to the patent group. Specifically, the number of patents per unit time is calculated based on unit time (for example, year) with respect to the patent group including at least two patents. - Next, in operation S320, the number of patents per unit time is calculated based on unit time and the time information with respect to the patent group. Specifically, in order to calculate the number of new technology-related patents per unit time, when there is no patent based on a predetermined patent classification depth and then a patent appears at a specific time point T, it can be seen as appearance of new technology. For example, when an initial patent appears in a corresponding unit using a USPC class unit or an IPC subclass unit, it can be seen as appearance of new technology.
- Next, in operation S330, the capability score is calculated based on the number of patents per unit time and the number of new technology-related patents per unit time. Specifically, a new technology score is first calculated based on the number of patents per unit time and the number of new technology-related patents per unit time.
- The following Equation (1) is an example of a method for calculating a new technology score (DFDi) per year.
-
DFDi=NPi*Wp+NTi*Wt Equation (1 - (DFDi: new technology score in year i, NPi: the number of patents per year, Wp: patent weights, NTi: the number of new technology-related patents, and Wt: technological (classification) weights)
- Meanwhile, the new technology score may be calculated using a depreciation coefficient in consideration of technological obsolescence. The depreciation coefficient is obtained by reflecting a reduction in the value of technology over time in consideration of a life cycle of technology. Specifically, the new technology score may be calculated by multiplying the right hand side of Equation (1) by a depreciation coefficient of the corresponding year (depreciation coefficient α≦1).
- Next, a technological cumulative score per year is calculated based on the calculated new technology score per year.
- The following Equation (2) is an example of a method for calculating a technological cumulative score (CDFDi) per year.
-
CDFDi=DFDO+DFD1+DFD2+ . . . +DFDi-1+DFDi Equation (2) - (CDFDi: technological cumulative score per year, and DFDi: new technology score in year i)
- Next, a capability score (FS) is calculated based on the technological cumulative score (CDFDi) per year.
- The following Equation (3) is an example of a method for calculating the capability score (FS).
-
FS=(CDFDn−CDFDt-1)/(CDFDn) Equation (3) - (FS: capability score, CDFDn: technological cumulative score in entire year n, and CDFDn-CDFDt-1: technological cumulative score after time point t)
- That is, the capability score (FS) may be defined as the ratio of the technological cumulative score (CDFDn-CDFDt-1) after the time point t to the technological cumulative score (CDFDn) in the entire year n as shown in
FIG. 9 . -
FIG. 4 is a flowchart showing an example of calculating a time score in operation S300 according to an embodiment of the present invention. - Referring to
FIG. 4 , in operation S350, the cumulative number of patents per unit time is calculated based on unit time and the time information with respect to the patent group. Next, in operation S360, a cumulative reference time point with respect to the cumulative number of patents per unit time is calculated. Next, in operation S370, a time score is calculated based on the cumulative reference time point. - The following Equation (4) is an example of a method for calculating a time score (TS).
-
TS=(n−k)/(n) Equation (4) - (TS: time score, n: entire period of time, and k: period of time until time point k)
- For example, the time point k may be set as a time point in which the cumulative number of patents is 80% of the total as shown in
FIG. 10 . - For the capability development of a convergence product, both a product launch time point and development types of the patents should be considered. Main patents with respect to the convergence product are generally registered before a corresponding product is launched, and when the product is launched, the number of registered patents is likely to be significantly reduced. Thus, an increase in the number of registered patents may denote an increase in the development potential of the corresponding capability and a reduction in the number of registered patents may denote a decline of the development potential. When the highest point (peak) of the number of patent applications associated with the convergence product occupies a specific position (for example, a position corresponding to 80%) of the total cumulative number of patents, the time score may be calculated as shown in Equation (4).
- Finally, a capability development index may be calculated based on the capability score and the time score which are calculated in operations S310 to S380.
- The following Equation (5) is an example of a method for calculating a capability development index (CI1).
-
CI1=FS*AFS+TS*ATS Equation (5) - (CI1: capability development index, FS: capability score, AFS: distribution of capability score, TS: time score, and ATS: distribution of time score)
- Referring again to

FIG. 5 , in operation S410, the number of patent classifications is calculated based on the number of at least one patent classification related to a single patent. - Next, in operation S420, weights of the number of patent classifications corresponding to the number of patent classifications are acquired.
- Next, in operation S430, a capability convergence score is calculated based on the number of patent classifications and the weights of the number of patent classifications.
- The following Equation (6) is an example of a method for calculating a capability convergence score (FC).
-
FC=ACS*(WS/Σ(NCi))*1−exp(−Σ(NCi)/100) - (FC: capability convergence score, ACS: distribution of capability convergence score, Σ(NCi): sum of the number of patents in accordance with the number of patent classifications, WS=Σ(NCi*Wi): weighted sum of the number of patents in accordance with the number of patent classifications and the weights, NCi: the number of patents when the number of USPCs including patents is i or more, and Wi: weights when the number of USPCs including patents is i)
-
FIG. 6 is a flowchart showing an example of calculating a service score in operation S400 according to an embodiment of the present invention. - Referring to
FIG. 6 , in operation S450, a service classification group including at least two services is transmitted to a user computer. - Next, in operation S460, selection information including information about the service selected from the service classification group is received from the user computer.
- Next, in operation S470, a service score is calculated based on the selection information. Specifically, the number of selected services may be handled as corresponding service information with reference to the selection information, and the service score may be created based on the corresponding service information. In this instance, the service score may be created using service weight information.
- Finally, a capability convergence index may be calculated using the calculated capability convergence score and service score.
- For example, the capability convergence index may be calculated based on distribution of each of the capability convergence score and the service score.
- Referring again to
FIG. 2 , in operation S500, an industry relation index is calculated based on the patent classification and the industrial classifications which are acquired in operation S200. Specifically, the industry relation index may be calculated using a relation score of heterogeneous industries and a relation score of homogeneous industries which are calculated based on the patent classification and the industrial classification. -
FIG. 7 is a flowchart showing an example of calculating a relation score of heterogeneous industries in operation S500 according to an embodiment of the present invention. - Referring to
FIG. 7 , in operation S510, an industrial distribution ratio based on the industrial classification. Specifically, the industrial classification is related to the patent classification in an industrial classification group such as SIC. The industrial distribution ratio may be calculated by dividing the number of industrial classifications by the total number of industrial classifications included in the industrial classification group. When the distribution ratio for each industry is high, the industry convergence potential is large, and when the related technologies are concentrated in a specific industry, the degree of technological convergence is high. - Next, in operation S520, at least two industrial classifications are selected in the order of larger number of patents related to the industrial classifications. In this instance, it is preferable that at least three industrial classifications be selected.
- Next, in operation S530, the degree of technological convergence is calculated based on the number of patents related to the selected industrial classification. The degree of technological convergence may be calculated by dividing the number of patents related to the selected industrial classification by the total number of patents included in the patent group.
- Next, in operation S540, a relation score of heterogeneous industries is calculated based on the industrial distribution ratio and the degree of technological convergence. For example, the relation of the heterogeneous industries is proportional to the industrial distribution ratio, but inversely proportional to the extent of technological convergence, and therefore the industrial distribution ratio may be divided into the degree of technological convergence to be calculated.
-
FIG. 8 is a flowchart showing an example of calculating a relation score of homogeneous industries in operation S500 according to an embodiment of the present invention. - Referring to
FIG. 8 , in operation S550, at least two industrial classifications are selected in the order of larger number of patents related to the industrial classification. - Next, in operation S560, a technological distribution ratio is calculated based on the number of patents related to the selected industrial classification. For example, the technological distribution ratio with respect to a first industrial classification may be calculated by dividing the number of patents related to a first corresponding industrial classification by the total number of patents included in the patent group.
- Next, in operation S570, a technological occupation ratio is calculated based on the number of patent classifications including the patent related to the selected industrial classification. For example, the technological occupation ratio may be calculated by dividing the number of patent classifications including the patent related to the industrial classification by the total number of patent classifications which can be related to the industrial classification.
- Next, in operation S575, the technological occupation ratio is normalized based on a correction coefficient of the technological occupation ratio.
- The following Equation (7) is an example of a method for normalizing the technological occupation ratio.
-
NTSn=TSn*Kn Equation (7) - (NTSn: normalized technological occupation ratio, TSn: technological occupation ratio, and Kn: correction coefficient)
(Correction coefficient (Kn(n=2,3))=Kn−1*(sum of the number of middle classification patents of analysis set of Topn/sum of the number of patents for each middle classification patent of Top1)*TPn
Correction coefficient of first corresponding industrial classification K1=1
Correction coefficient of second corresponding industrial classification K2=K1*(the number of patent classifications including patents related to second corresponding industrial classification/the number of patent classifications that can be related to first corresponding industrial classification)*TP2
Correction coefficient of third corresponding industrial classification K3=K2*(the number of patent classifications including patents related to third corresponding industrial classification/the number of patent classifications that can be related to second corresponding industrial classification)*TP3) - In this instance, it is preferable that the correction coefficient be differently applied for each rank of corresponding industrial classifications.
- Next, in operation S580, a relation score of homogeneous industries is calculated based on the technological distribution ratio and the normalized technological occupation ratio. For example, the relation score of homogeneous industries may be calculated by dividing an average of the normalized technological occupation ratios by a sum of distribution ratios for each industry.
- Finally, the industry relation index may be calculated using the calculated relation score of heterogeneous industries and relation score of homogeneous industries. For example, the industry relation index may be calculated based on distribution of each of the relation score of heterogeneous industries and the relation score of homogeneous industries.
- The present invention may be applied to measurement of the degree of convergence, estimation of convergence properties, calculate of convergence index, and services using these with respect to products or technologies or the related patent group.
- In addition, the present invention may be used in systematically promoting convergence industry development.
- Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in this embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
